Just wondering,

Dumb newbie question here but does size matter for the size of rider?

I know logically bigger foils will lift more at lower speeds and smaller foils can have potentially high top speeds etc etc but I was wondering, does a bigger rider need or is it preferable to have a bigger front foil?

I get that a bigger slower foil is easier to learn on but does the size matter or is it less of a factor in the bigger picture of foiling?

Thanks for any replies.

cheers,

Robbie :)

A foil will produce more lift as it speeds up through water.
but that lift can be controlled by AoA
to a point.
the rear stabiliser helps to control this AoA to a point.

the smaller wing you can get away with using for the style you are using it for the lower the drag and more efficient it is.

But in the end size does matter.
at least that's why my wife married me, she says.

Yes bigger riders need a bigger wing.

My personal theory: wing loading. According to the theory, for a given wing, as you instead its load you increase the crushing speed.

I'm other words, you lose the bottom end and gotta ride faster.

Bigger wings are more stable, better low end, easier to do stuff on.

Don't mess about Robbie, get a 1000-1200cm2 wing and get on with it

Nah don't believe it, your getting a foil.

Just be careful, general speaking you need a bit more wind to get the faster foils working.
Knowing where you kite a bigger foil would be the way to go.

I have a Airush foil you can have If you decide you want to go a bit faster. (600mm mast- hanging up in the shed collecting dust)
I would also take the mast length into consideration as well. Long walk up there before it's deep enough to start.

I have more fun on a bigger front wing.

... haha yeah, believe it, I'm finally doing it. I was using my Sector as an excuse, I though while its going ok that'll do for my light wind riding but my sector's fin boxes are finally giving up on me so,,,, no more excuses now. Besides, gotta get with the cool gang and join the dark side!

I've borrowed a mates North speedster setup and so far so good,,,,ish! Had my arse handed to me,,,, taking ones head from 9 foot above the water and accelerating it at warp speed in a circular motion towards said water is a sight to behold apparently,,,,, funny a sh!t they tell me!

Getting up and foiling along in flat water is so far so good,,,ish,,,but the moment I get a bit of swell I breach the foil over I go. So, I still have no height control yet.

I'd love to take you up on the foil offer for sure, that'd be great, cheers!

Well if you can get going on the north setup then a bigger say axis wing will be a piece of cake. Foiling is perfect for you big fella.

That should have been cruising speed, not crushing speed. You do get a beat down though...

1200cm2 if you're a big fella. Mine is 1500cm2, FYI.

... yeah the getting up and riding didn't take that long luckily which surprised me. I guess bashing one's head into rock hard water at speed tends to help motivate you to get better quickly hey!!!

Controlling the height when I sped up is my next challenge it seems,,, might be because I might have too much kite up I think. When I managed to go nice and slow with a bit of steadiness I managed to steer myself downwind so I could avoid some rocks upwind of me.

But man, lean against the kite and push down hard on the front foot,,,, friggen warp speed with all this eerie silence knowing the imminent uncontrolled dismount coming is gunna hurt,,,,,,yep, pretty cool actually this foiling malarkey!!

You have always done epic long voyages on your nugget and sector. Imagine what you can do with a foil!! Plus with the foil you will do it with more speed and less bash and crash on your body.

If you get that crazy speed bleed it off by directing downwind but also lift your kite higher and depower of course. The second bit is important because I used to head downwind but the kite would also drop into the power zone and then you seem to have no control of the speed. Kite just keeps hunting the edge with more power! Especially with a kite that pushss forward in the window.

The bigger foils as suggested will allow you to more easily stay on the foil but also at lower speeds. That north setup (I've tried it) does require some speed to get on the foil and also can generate further speed quickly.

Oh and as you head downwind you will generate more speed so push forward and bend the knees!!

The other option is to hawk upwind... again watch thekite as it will naturally drift lower and really really bend the knees. Cause you will naturally dig your heels in.

So the big foil will allow you to get foiling at next to no speed and also if one gets too much speed bleed it off whilst still remaining on the foil.

It also has a much much greater degree of error allowed to control yaw.

... and they go fast enough when needed for us cruisers.

Bend the knees !! This transfers weight across the longditunial axis (back to front of board) and away from your heels... which is what you will conditionally do when you get speed.

The faster you go the more you bend your knees. Think poo stance bahahabbababa

dont go too big though as the bigger you get the more front foot pressure you need and this can get tiring with a kite.

Talk to the big K (above) Robbie, he's all over it man and big dude like yourself.

... great info, thanks dude.

I kinda stumbled onto the 'bending of the knees' thing with speed because it felt like the right thing to do when I picked up too much pace but, for some reason, thought I read somewhere, it was a wrong stance, so fought myself from doing it but I kept naturally going back to it, especially, as you rightly say, when kite drifts back and powers even more. I guess I read it wrong or more likely, remembered wrong.

Looking forward to the next session now.

Cheers,

Robbie :)

To add with the bigger foil (and a Sup Surf type foil to be hoenst), all the gybes etc are much easier to learn because of the fact you won't stall out as easily. You can gybe at slower speeds and still be foiling. That's why eddie mainly uses his freeride larger foil now I would suspect.

Can't wait to see your latest GPS map, it's gonna thoroughly destroy all the sector sessions over the years .:)

But yeh...some beatings beforehand to be had.

Reckon that speed control is the main thing to master and with your advanced kite skills the rest won't take long.

And glide -- you don't need to rely on the kite pulling you around the whole way, you can just ride the board. Today I was on an 8m Switchblade while the racer boys were on 15m kites :D

Woohoo, he's finally bit the bullet Eppo!
Pretty soon there will gps tracks going 100 kms !

In my experience , when overpowered I bled off speed by going upwind. Kind of a hangover from my windsurfing days. Only problem was then realising I had to get back downwind.
Actually , I sometimes did go downwind and bring the kite up but it scared the **** out of me.

Body positioning improves as you go. Front leg bent , then back leg with it.

Not sure about how far you take the size of foil thing when compared to size of person. We reckon my jshapes cruzer is about 950, bigger than the speedster which I have had a shot on ... 1200 seems bloody big from there but Kami swears by that size so I reckon there is also a design effect . More in it than just purely the size of the foil .

Depends on your goals -- minimum kite, chasing swell and waves: go bigger.

1000cm2 for regular sized kiters. If you're 100kg or over, start with 1200. Mine's 1500cm2 but it was the smallest SUP/Surf wing at the time. I've gotten used to it. I wouldn't want to go much wider because I keep poking wing tips out at inopportune moments (but I'm still using a 75cm mast) but the 720 doesn't have the same amount of glide. Also means I can muscle it around some without having to rely on the kite...

What area is your surf wing, Eppo?

I'm still using the axis 680. I assume that means 680cm squared in area. I only weigh 78-80kg now though. (75cm mast as well).

Thats both for kiting and prone surfing. It's been a hard slog prone surfing on such a small wing. I basically paddled, caught a wave then ventalated / yaw over for a good month. Lots of crazy wipeouts. These have reduced now but still working on taking off on critical sections.

Plus side is, the smaller wing is super fast and agile on the wave. Downside is it lacks natural glide when the wave / swell line dissipates. I can pump okay through the lulls back to shore but I'm yet to be able to pump back out. That's where a bigger wing would help. 750 would be better but I'm determined to use just one wing.

Dont you use a 820 ? So is this the area or is it just relative sizing ? Looks like you are saying it's 1500cm squared. So what's my 680 then ??

ps some swell today so about to hit it !!

pps Eddie Robbie won't know himself!! He will also be cranking in no time as that guys a distance machine !!

Had to look it up...680mm wide wing, 1048cm2 projected area. Robbie might try the 750...unless he really wants to just lay the miles down, then perhaps the kite foil?

I reckon an 820 minimum to be honest to start. 750 is where a lot is prone and suppers are going to. reckon with his weight 820 minimum. Maybe a 950 and a 750 for speed and distance down the track. ?? The 680 is pretty small hey. The heavier bloke I orone with struggles to get enough lift on it and he's only 90 odd and that's a thin weight for him ... tall dude.

You can have 2 front wings with equally same ccm2

If one has thicker profile near the front , and the distance from front to rear is longer on the top of the wing ..like an air wing...then you will have more lift than the wing with a shorter distance along the top.

It's more about shape than size that gives a wing greater hydrodynamic lift.

Size enhances stability .
Anhedral shape offers great stability over dihedral and gives an acceleration feel through a turn.

Dihedral gives a feeling of slowing through a turn , but likes to naturally return to level with little input from rider.

It's a bit like concave and convex shapes on the bottom of a board.

They use both shapes , one front one rear to blend both caracteristics into the overall foil performance.



That's why fronts are usually
Anhedral shape.
And rears are dihedral .

I'm still using the axis 680. I assume that means 680cm squared in area. I only weigh 78-80kg now though. (75cm mast as well).

Thats both for kiting and prone surfing. It's been a hard slog prone surfing on such a small wing. I basically paddled, caught a wave then ventalated / yaw over for a good month. Lots of crazy wipeouts. These have reduced now but still working on taking off on critical sections.

Plus side is, the smaller wing is super fast and agile on the wave. Downside is it lacks natural glide when the wave / swell line dissipates. I can pump okay through the lulls back to shore but I'm yet to be able to pump back out. That's where a bigger wing would help. 750 would be better but I'm determined to use just one wing.

Dont you use a 820 ? So is this the area or is it just relative sizing ? Looks like you are saying it's 1500cm squared. So what's my 680 then ??

ps some swell today so about to hit it !!

pps Eddie Robbie won't know himself!! He will also be cranking in no time as that guys a distance machine !!




Had to look it up...680mm wide wing, 1048cm2 projected area. Robbie might try the 750...unless he really wants to just lay the miles down, then perhaps the kite foil?



The new Axis HA 900S wing could also be an option, @ 1184cm2 it sits between the 680 & 750.
Very fast & apparently pumps better than the 920, I'm hoping this is the one wing that does it all.

Thumbs Up

I went from 1500cm2 to the AXIS102 (2000cm2).

I use the 102 for kite, SUP and now Wing wang foiling. One foil to rule them all.

Super slow, but you can go from 8 knots, generally use a smaller kite and feel/ride the swell from one foot up.
